The Taber Stiffness Tester is an essential tool designed to evaluate the bending resistance of paper, paperboard, and other high-grammage materials. With applications across industries like packaging, medical devices, electronics, and quality inspection, this instrument helps manufacturers ensure product durability and structural integrity. The Taber Stiffness Tester provides accurate, reliable measurements, making it ideal for quality assurance processes where precise stiffness data is critical.
Applications of the Taber Stiffness Tester
The Taber Stiffness Tester is widely used for measuring stiffness in materials that require strong resistance to bending, such as packaging materials, labels, and structural layers in electronics and medical devices. With its ability to accurately assess the bending strength of materials, it aids industries in ensuring compliance with performance standards, product longevity, and consistency in packaging quality.
Testing Principle and Measurement Process
The Taber Stiffness Tester operates by clamping a test sample and bending it through a predetermined angle to measure the resulting bending moment. The bending moment, expressed in millinewton meters (mN·m), directly reflects the material’s stiffness. For general materials, a 15° angle is standard, while a 7.5° angle is available for sensitive materials prone to permanent deformation at larger angles. The Taber Stiffness Tester’s design ensures precise bending length and speed, guaranteeing consistent results for quality control and research purposes.
